Ravens, Bills, Cardinals... those are the top options I have to choose from.
I have the Packers, but need to get a backup, and a lot of my other positions are pretty shored up with locks to start each week, so I can pick up a best option available for a guy on BYE as I need, but would like to stash a back up D if the week to week matchup looks favorable, and I think someone in my league will grab one of these D's if they're sitting for much longer...

Thoughts? Who would you go with and why? I have mine, just trying to get some feedback / 2nd opinion...
